Abstract

1,146,866. Twisting apparatus; false-twist apparatus. BATTELLE DEVELOPMENT CORP. 20 Dec., 1966 [23 Dec., 1965], No. 57066/66. Heading D1D [Also in Division E2] A clamping device comprises a rigid cylindrical body 1 having a passage 2 extending axially therethrough, a resilient tubular member 10 mounted in the passage and a plurality of wear-resistant flexible filaments distributed about the axis of the body in substantially parallel alignment to form a bundle 8 and flaring outwardly at one end of the tubular member to form a funnel, the arrangement being such that upon introduction of an object of a substantially circular cross section into the funnel to be gripped by the bundle of filaments, the filaments are forced apart along the bundle to surround and engage the object and to enlarge the internal diameter of the tubular member whereby the latter assists the filaments each to exert a radial clamping pressure on the object. As shown, the filaments which may be made of steel or glass, are anchored at the funnel end on a member 12. The member 10 may be made of rubber a synthetic foam. In a similar arrangemeant, Fig. 5 (not shown), adapted for use as a twisting member in means for spinning texile fibres, into yarn, the rigid body (20) is secured to a pulley (21) which is driven by a belt (22). The device may also be used for false twisting.
